For these customers who do not have a closed laminating workshop, the noise that generated by the no bottom paper film is a very troublesome problem. Especially when the laminating workshop is very near to the office. The noise that generated by the lamination makes the office noisy and seriously affects the office environment. It causes the office staff be unable to concentrated on work, error-prone, difficult to communicate and answer the phone, people are restless and so on.
How does the noise generated during no bottom paper film lamination?
According to our long-term observation, testing and research, it is found that the noise is generated by the bounce of the film at the moment of uncovering. The size of the noise is related to uncovering bar’s size, angle, surface hardness, glue viscosity, peeling force and speed of the film.
In general, the larger the uncovering bar, the larger the area of the uncovering film and the bounce, and the greater the noise. The stronger the viscosity of the glue, the higher the peeling force, the higher the strength of the bounce and the greater the noise. The sharpness of the noise is related to the amplitude and frequency of the film bounce.
How to reduce the noise during film laminating?
The best way, of course, is to perform the release treatment on the surface of the bottomless film, reduce the peeling force and make silent no bottom paper film. However, the no bottom paper film that be subjected to the release treatment is relatively expensive and can only be used in some special occasions.
For the ordinary no bottom paper film, it is necessary to reduce the peeling force to reduce the noise during laminating, and also to ensure that the glue has a high enough viscosity to ensure the reliability of the film. This is contradictory and it is difficult to reduce noise unilaterally.
Can we find a way to reduce the noise from the no bottom paper film laminating machine?
Some people have tried to install a muffler on the laminating machine to reduce the noise, but the effect is not obvious and it is not convenient to use.
From the internal cause of noise, it is necessary to reduce the diameter of the uncovering bar to reduce the bounce area of the film during film uncovering, thereby reducing the noise. It is also possible to increase the surface softness of the uncovering bar to reduce the vibration strength of the film, absorb some vibration waves, and also have a certain effect of reducing the film noise.
Centainly, the most ideal way is to set up a closed laminating workshop, or place the laminator away from the office, it doesn't matter even if there is some noise during the laminating .
After all, the cost and efficiency advantage of the no bottom paper film is obvious!
